74 This project requires all contributors to assert that their contributions
75 are provided in compliance with the terms of the Developer's Certificate
76 of Origin 1.1 (DCO):
77
78 https://developercertificate.org/
79
80 To indicate acceptance of the DCO every commit must have a tag
81
82 Signed-off-by: REAL NAME <EMAIL>
83
84 This can be achieved by passing the "-s" flag to the "git commit" command.
85
86 To bulk update all commits on current branch "git rebase" can be used:
87
88 git rebase -i master -x 'git commit --amend --no-edit -s'
